Options for incentivizing demand for biokerosene and impacts on aviation and the economy
Aviation causes around 2% of global anthropogenic CO2 emissions, and without additional measures this figure is set to rise substantially the coming decades. Further growth of aviation emissions is hard to square with climate targets such as those agreed to under the Paris accord, where countries expressed their ambition to halt the rise in carbon emissions as soon as possible, reversing this trend and achieving net zero emissions by the second half of this century. The measure with the greatest potential to reduce aviation CO2 emissions is use of fuels with low lifecycle emissions, such as advanced biofuels produced from agricultural and forestry residues. If aviation is to make any meaningful contribution to global emissions reduction, it is therefore of the essence this sector works towards using a growing share of alternative, renewably sourced fuel. Given the price difference between fossil kerosene and biokerosene, government policy will be required.
